Pwp Temeprature distribution during circulation

[molossian]

I'm trying to run the example in the documentation page https://pwptemp.readthedocs.io/en/latest/circulating.html

By just copying and pasting the code, I get the following error: "argument of type 'Well' is not iterable"

Can you help me ? It would be so useful for me to use this software! It has a great potential!! Thank you!
